An uneven surface refers to a surface that is not flat or smooth, featuring variations in height and texture. This can include bumps, dips, or irregularities that can affect how objects move across it. Uneven surfaces are commonly found in natural environments, such as hiking trails or riverbeds, as well as in constructed areas like roads and sidewalks. The presence of an uneven surface can impact safety and accessibility. For example, it may pose challenges for wheelchairs or strollers, making navigation difficult. Additionally, uneven surfaces can increase the risk of slips and falls, highlighting the importance of proper maintenance and design in public spaces.
